In The Netherlands, major infrastructure projects are assessed using cost-benefit analysis, following official guidelines. Until recently, the reliability of travel times could not be included in the cost-benefit analysis, because the corresponding monetary valuation was unknown. In recent years, the literature on valuing reliability of travel times was reviewed for the Dutch transport ministry. The outcomes of this were discussed at an expert workshop, which led to an agreement on preliminary monetary values for passenger transport. A key concept is that of the reliability ratio. This is defined as the value of reliability (measured as the standard deviation of travel time) divided by the value of travel time itself. For freight transport a follow-up study was carried out, which transforms the results of earlier stated preference research into a reliability ratio. The paper presents and explains the preliminary values, focussing on the derivation of reliability values for freight transport. It also describes how these values can be used in practical project evaluations.

This paper develops an analytical model for the assessment of the cost performance of a given logistics network operating under regular and irregular (disruptive) conditions. In addition, the paper aims to carry out a sensitivity analysis of this cost with respect to changes of the most influencing factors. In particular, this is expected to investigate the vulnerability of this network with respect to particular disruptive events. The logistics network under consideration consists of the manufacturers and retailers/consumers as the origin and destination nodes of the goods flow concerned, and the transport system (links and services) connecting them. The nodes are characterized by the goods’ production and consumption rates, and the level of inventories, and related costs. The transport system is characterized by the transport mode that is exclusively used in the network, its frequency of service, the goods’ delivery time (speed), and the related costs. Irregular conditions are characterized by the intensity of the impact and duration of the disruptive event, which, in the given case, is assumed to completely cut off the transport services in the network. The model uses inputs reflecting these characteristics. The output consists of the network’s total and average cost per unit of goods, which is estimated depending on the type and delivery frequency of the transport mode that is exclusively used, and on the duration of the disruptive event. The model is applied to the generic hypothetical logistic network using data from the European logistics networks.

The integration of ports within logistics and supply chains has become a major issue for both public and private players worldwide. Notably, the role of intermediaries in establishing efficient integration within transport chains in which ports are embedded is not well-known. International comparison is limited by the drastic lack of quantifiable information about inter-firm linkages and intermodal operations. Based on a European business database, this paper analyses the modal portfolio and employment distribution of about 8,000 transport firms, intermodal operators, and freight forwarders among 80 European ports. It allows measuring the degree to which different industries such as port activities, logistics, warehousing, road, sea, river, rail, and air transport, integrate within firms and within ports. Main results of the quantitative analysis show that transport integration and port performance have significant interdependence, but this is influenced by hinterland size, accessibility, and regional legacies differentiating Northern from Southern ports.

The trend in many countries is to outsource maintenance with competitive tendering. The design of the tender is then a crucial issue. A new type of tendering contract, called "Integrated Bridge Maintenance", was introduced in one experimental area in Sweden. In this case bridge maintenance is separated out from the standard road maintenance contract. A pilot project has been running since 2004 for all bridges in Uppsala County with about 400 bridges. The experiences and lessons from this pilot project are presented here, and analysed from a transaction cost perspective. An important feature of the contract was that it contained a combination of measures that should be carried out and properties of the bridges that the contractor was responsible to maintain. This created a balance between predictability and flexibility for the contractor. The client was satisfied because of increased competence and a low price. The latter can partly be explained by the possibility for the specialised bridge crew to get additional work from other sectors. One problem was that some properties were difficult to measure, which led to some controversies. As information about old bridges always are incomplete a partnering structure need to be built into the contract. Experience has also shown that a conscious policy to maintain long run competition is important. The general conclusion is that the project was seen as successful and as creating more "value for money".

The current variability in weather and climate is posing a challenge for transport infrastructure. However, during the past decade the need to adapt to a changing climate has attracted increasing attention. This paper summarises a case study on the future vulnerability to climate change of the Swedish railway transport system and its adaptive capacity. The combination of a long time horizon in planning and an expected increasing demand for rail traffic raises many questions regarding how adaptation to climate change can be accounted for in future planning, design and management of railways. The case study was essentially based on interviews with key personnel within the Swedish Rail Administration. Views on vulnerability and adaptation to climate change were documented, and the need for improved methods to assess the vulnerability and adaptive capacity related to climate change for the Swedish railways was addressed. The conclusions of the paper are addressed to the European railway context at large. Firstly, systematic mapping of current climate vulnerabilities and their consequences is important in order to guide the implementation of adaptation measures. Secondly, climate change should be considered in the early stages of planning and included in risk and vulnerability assessments. In assessing future conditions with the aim of prioritising adaptation measures, current methodologies should be complemented with more future-orientated tools. When designing adaptation measures, the effects of potential goal conflicts should also be assessed, in order to avoid the implementation of counter-productive measures. The possibility of creating synergies with climate mitigation goals and other environmental goals should also be investigated.

In another recent book review published in the European Journal of Transport and Infrastructure Research, David Banister (2008) wrote “Having read this book, one is left with a feeling that the important issues raised should have been at the forefront of policy debates for many decades, not just now”. I have to confess that I have exactly the same feeling after having read “The Future of Intermodal Freight Transport”. Indeed, this book explores the important challenge of increasing the scope of intermodal freight transport, and I remember the same question was already an issue in the 80', when I was a young researcher. This reflection, however, does not affect the overall quality of this book.
